Abstract

A data reader (300) includes: a memory card interface (344) communicating with a memory card (200) in which is recorded data such as video, the recorded date of that data, and a reproduction time limit of that data; a real time clock (330) detecting the current date; a display unit (352) reading out data from the memory card to display video or the like; and a CPU (320) comparing the current date detected by the real time clock (330) with the recorded date and reproduction time limit of the data recorded in the memory card (200) to determine whether reproduction of the data recorded in the memory card (200) is allowed or not.
